So I'm now waiting for AJD-JimKam: if JimKam wins or ties, he'll win the championship; otherwise AJD still has an outside chance of winning the championship (by winning all 12 sets of his remaining 3 matches) or tying with me (by winning 11 sets).
I also kept track of wins in each separate category -- right now, if my calculations are correct, qdread has won the E/F championship, and the other 3 are still undecided. Listing only those who can win, in the format [wins + number of remaining games]
Base: antony (6+0), moomoo (5+1, won H2H), MTom (3+3, would share tiebreak)
Echoes: JimKam (5+1), AJD (4+3) <- that'll be decided by their H2H match too
E/F: qdread (5+0) won H2H against JimKam (4+1) and MTom (2+3)
E/F/C: JimKam (5+1), AJD (2+3) -- antony (5+0) lost H2H against both
I'd be happy to restart a championship right after this one is finished, I think this is a lot of fun indeed.
